No meeting participates afer sync'ing via Desktop Manager

If I don't use the Blackberry service to sync my calendar but use the Blackberry Desktop Manager instead, all my appointments/meetings are synchronized but I can't find the meeting participants in my Blackberry .

Windows Mobile or my old Plam Treo 650 as well show title, time, location AND participants (plus meeting details).

Do you have an idea, how to show the participants at my Blackberry as well without OTA synchronization?
